QO2201021 - 20 Amp Circuit Breaker

QO2201021 - 20 Amp Circuit Breaker

The QO2201021 is a 20-amp, 2-pole Type QO plug-on circuit breaker equipped with a 120VAC shunt trip device for applications that require remote breaker operation. In addition to providing protection against overloads and short circuits, the built-in shunt trip allows the breaker to open from a remote signal, making it a practical choice for emergency shutdown systems, fire alarm integration, and other control applications. Its plug-on design makes installation straightforward in compatible Type QO load centers and panelboards, while the 10kA interrupting rating at 120/240VAC provides dependable protection for a variety of commercial and industrial branch circuits. If you're replacing an existing breaker or maintaining an electrical distribution system, this model offers the convenience of remote tripping without sacrificing the reliable performance expected from a Type QO breaker.
